If I absolutely have to have a yardage this is the rangefinder I use... I have had it against all 3 generations of G7, all the SIGS and the Leicas... This rangefinder out does them all... Have ranged trees at 4300 yards... Took it out in the smoke and it was the only rangefinder that ranged my 1720 yard target... none of the others would produce a reading.... Why am I selling it then... I have the SIG binos and a kestrel. This is what I have chosen to use .. If this had a ballistic program it would not be for sale..I will be traveling from Butte Mt to Phoenix AZ . latter this week if anyone is interested in it and wants to try it out... Dave
